Thenefore, in urder to reduceithe'floor-space to'he taken up byfloraiding machines of this characterzand 1 also to reduce the Weight to the minimum, 1

have devised simple practical way of i utilizing this, space which is withinthe raceway 'ofthe larger-size machine by: mounting another braiding unitinthis center portion;

which unit ,may he I started. and stopped gindependently of;jthe]larger unit hut which maybe, driven synchronously with fthe larger 1 unit from the 'mai-n driving shaft thereof,

and ;;t-he --vt;ol-lowin;g isa detailed description] 7 legs 11 and on thistable is supported the raceway plate '12 which is provided with an outer raceway 13 of the larger size machine, which extends part way around the circle of the raceway plate 12 being of the type arranged for the braiding of flat braid. A;

raceway formed on this relatively large circle must necessarily leave a. substantial central portion unoccupied, in the ordinary braider, and in order to utilize this heretofore unused space to advantage, 1 have formed" another or inner raceway 14 within, the outer raceway 13 in the same raceway plate 12. The turn quoits 15 of the inner raceway may be set opposite to the turngquoits 16 of the outer raceout those of one set interfering with those way or they maybe set adjacent to them if desired and in either case the yarn leading from the difi'erent carriers may be led to their respective braiding points withleading from the other set of carriers. The yarn 19 from the carriers 17 of the outer raceway being led along their selvage needles V 18 to be braided together at the point 20 and thence led over the roll 21 and the set of rolls 22 in the take-up head 81 to be wound on the reel 23, while the yarns 24 from the carriers 25 are led over the selvage needles 26 to be braided at the point 27 thence over theroll 28 and series or rolls 29 in the take head 82 to be wound on the reel 30. Both of these take-up heads are mounted adjacent the tIXlEll center of the machine and both are supported on the single take-up head supporting frame 83 which is supported on the cross-bar 84 and back brace 85." It is obvious that the smaller raceway 'may be continuous in itself to permit the braiding of tubular braid thereon, if desired.

The 'powerfor driving the two units is herein described as being adapted to be applied through a large pulley 31 mounted on r. the main drive shaft 32 which has its bearings at 45 and 46, re'spectively, the outer end of this shaft 32 transmitting its power through the m'itre gears 33, clutch members 34, and sliding clutch member 38, uprlght .shaft .35 and gear 36 to drive a train of horn gears 37 for'imparting a braiding motion to the set of carriers 17 p This main shaft 32 may also be employed .to transmit motion through mitre gears 39,

"clutch member 40, movable clutch member 41, uprightshaft 42 andgearr43 to the train of horn gears 44 to impart the necessary braiding action to the set of carriers mounted in the inner raceway 14.

In order to impart a rotary motion to the take up I have mounted a pair of gears 47 to receive motion from the upright shaft 42 and transmit the same through shaft 48, mitre gears 49, upright shaft 50, worm 51, vorm gear 52, gears 53 and 54, to horizontal shaft 55 for the purpose of rotating the take up rolls 29, also transmitting power from the lowermost of this set of rolls 29 through pulley 56, belt 57, pulley 58 to theYreel 30, alsoon this upright shaft 50 I have'mounted an operating handle 59 by which the mechanism of the smaller unit may be operated by the attendant when desired, in dependently of the driving power from'the main shaft; also, a set of take-up rolls 22 are arranged'to receive power from the up right shaft 35 through worm 60, worm gear 61, gears 62, large gear 63, horizontal shaft 64 for the purpose of taking up the braid work as produced by the outer braiding unit,

which power is transmitted through the lower roll of the group 22 through the pulley 65, belt 66, pulley 67 to the take-up reel'23. Also, this-unit may be operated by hand if desired by manipulating the handle 80.

The stop mechanism for each .unit is en'- tirely separate, that, actuated by the carriers of the larger braiding unit being a lever 68 pivoted at 69 having an inwardly extending loop portionZO adapted :tobeengaged by the usual tension weight on the carrier (when.

the end is broken to throw this'lever out of engagement with the upright lever 71 to permit the clutch member 38 to drop out of engagement with the member 34 thereby disconnecting the power from the larger unit permitting its mechanism to stop until the operator has pieced up the end and restored the mechanism to its running position. I t

When a yarn end breaks in the smaller or central unit the knock-off lever 7 2 pivoted at 73 is engaged at the point 7 4 and thrown outwardly to release the upright lever 75 permitting the clutch member 41 to drop out of engagement with the clutch member 40 to arrest the action of the smaller braiding unit untilthis end is pieced up and the parts again vrestored to operating position.

It will also be noted that by' the arrange ment ofthe two different raceways that the stop motion of" the inner raceway is so positioned as to arrest the carrierwlth the broken end, at a point directly at the front of the machine, where it is most accessible to the operator. c

- fhe braided workafter being taken up by the take-up head may be taken off by the reels '23 and 30 shown in Figure 4, orby suitable take-01f rolls 7 6 and 77 on shafts the other,

different character, again by my improved arrangement of braiding units practically the whole of the space now occupied bythe second or smaller braiding unit has herespace'bymy improved construction is now utilized, and in addition I now'emplo'y the same bed, legs, main driving shaft and pulley used bythe larger unit, for the smaller unit, thus saving the weight of these parts in the construction of the second unit by eliminating the necessity of duplicating the In addition to the above itis also obvious that by mountingthe machine in a more compact space more machines may be operated by a single attendant.
